I always look for the polarized tag when shopping for sunglasses. Great for driving and fishing. Interesting that you find how many other things have polarized lenses in every day life when your looking through two lenses that are out of phase. Like the numbers disappearing on the LCD display at the gas pump.

Every time I look for polarized sunglass clip-ons, I check them carefully. Many pairs are "out of phase" and that gives me a headache.
